Abstract
The proposed application explains how both viscous phenomena combine at each step of the calculation. Just after the excavation, water overpressure decreases near the gallery, approaching zero due to the damage, and thus increases permeability. The viscosity is then controlled by the solid skeleton creep rate. Later, the redistribution of hydraulic pressure becomes more important and permeability again plays a major role.
